This is a piece I just completed. The first version got ruined when I was prepping it for shipping. Which was kind of good, cause I did not like it. Doing a whole new one with a total different direction resulted in this one. Which will be mailed out tomorrow. Commisioned Name arroyo2 by HRSG, on Flickr

This is really gorgeous! I love the wavy lines you always seem to achieve. This may be a dummy question, but the tiles are square, right? You just lay them out on curves and grout? It's so organic and non-linear, which is such a (pleasant!) surprise with mosaics...
